Can't connect to my realm

I own two realms. For the past two days I've been completely unable to connect to my realms or my friends, I can't make new realms, and I can't manage my realms most of the time. The other members can usually join after a couple tries but have also been having some issues. I've tried everything I can think of: Reinstalled Minecraft, reset my router, set my Xbox to offline and back. Nothing has worked. So now I'm assuming it's a realms issue.
